An excellent inverter for home

After my previous MGE broke down (battery and electronic after many years of loyal service), I turned to APC and BE700G-GB model.
No complaints about the delivery, perfect as usual with Amazon.
Quick unpacking simple commissioning: the battery was charging one day and then the UPS into service.
I have connected: fixed my PC's screen + my + livebox my network switch.
I then installed the software and I must admit it's a little disappointment.
Certainly it gives me the basic information expected from an inverter, but I lost a lot of features that I had with my MGE: eg all the historical curves on the voltage levels.
In addition to the icon of the systray continuously displays an exclamation point indicating a communication error (also nonexistent ....)!
That's why I did not put 5 stars ...
In summary: good material and some lightweight software!
